Otherwise, if the DECT earphone 4 has already departed from the DECT host 3 when there is an incoming call. The user can answer the incoming call by using the button unit 410 on the DECT earphone 4 to control the first central control unit 301 via the DECT wireless communication technique. The first central control unit 301 receives the incoming call signal S1 by driving the electronic switch unit 302 to be in conduction. Then the user can communicate mutually with a plurality of remote users in private via the DECT earphone 4 associated with the operations of the electronic switch unit 302, the first central control unit 301, the communication network unit 304, the first DECT wireless unit 309 and the DECT earphone 4 of the DECT host 3.
To sum up, the DECT wireless hands-free communication apparatus of the present invention is linked with the PSTN for dialing a local call. The present invention can achieve the goal of mutual-communicating in hands-free way via hands-free transmitter.
